STOVEPIPE-COUPLING.

To all whom it may concern:

Be it known that I, ELwIN J. BABBITT, a citizen of the United States,and a resident of Onaway, in the county of Presque Isle and State ofMichigan, have invented certain new and useful Improvements inStovepipe- Couplings, of which the following is a specification.

My invention relates to improvements in couplings or fastenings forpositively looking together the ends of stove pipe sections, and has forits object to produce a simple, cheap and efficient device for fasteningtogether the ends of stove pipe sections.

My invention consists of a detachable and removable latch which may beapplied to the ends of stove pipe sections; it consists further incertain novel features of construction, arrangement and combination ofparts as will be hereinafter fully described and pointed out in theclaims, reference being had to the accompanying drawing in which Figure1 is a sectional view showing application of the lock or latch, and Fig.2 is a perspective view of the lock' or latch device detached.

In the drawing A, A represent two stove pipe sections telescoped attheir adjacent ends, the end of section A being crimped as shown at a;to this section is secured the latch or lock which consists of a mainportion B made of resilient material, preferably metal, having the end Bbent over to grasp the end of the section A; the opposite end of theclasp or look is bent back upon itself or thickened as at B andprojecting upwardly from said end is the stud B said stud springingthrougha small aperture a in the section A.

To make a coupling using my improved device, the latch or lock isapplied by slipping the turned back end B over the edge of section A,and allowing the stud B to spring up through the aperture a; the section A which is provided with an aperture or opening a a suitabledistance from its end is now telescoped over the section A and when slidsufficiently far the stud B will spring through said aperture a and thesec tions of the pipe will be securely locked together againstlongitudinal movement as Specification of Letters Patent.

well as against any independent turning of the two pipe sections.

My improved latch or lock may, of course, be used to connect the lastsection of pipe with the stove pipe thimble and when used at such pointas well as at any oint will act to prevent sagging as the body portionof the latch is sufficiently rigid to perform this function.

The latch or look may be manufactured, and sold separately, so as to beapplied to any stove pipe by simply having the necessary aperturespunched in the sections. As the material from which the latch or lock ismade is resilient the bent back portion forms a clasp which grips thesection A at its edge.

It will be seen that my improved latch or lock is positive and cannot beaccidentally displaced. To separate two sections of pipe it is necessaryto depress the stud by force below the outer section before it can beseparated from the adjacent section.

I claim 1. In a coupling for pipes, a latch or lock consisting of aplate of resilient material bent at one end to form a clasp to grasp theedge of a pipe section, and a stud project ing upwardly at its oppositeend to pass through said pipe section and an adjacent telescoped pipesection.

2. In a coupling for pipes, a latch or look consisting of a resilientplate having a spring clasp at one end adapted to grasp the edge of onepipe section, and a stud project ing from its opposite end adapted tospring through said section and an overlying end of an adjacent section.

3. The combination with a pipe section having a hole or opening adjacentits end, of a latch or look plate having at one end a clasp adapted tograsp the edge of said section and a stud at its opposite end adapted tospring through the aforesaid aperture, and an overlying adjacent pipesection having a hole or opening adjacent its end adapted to receive thestud of the lock or latch.
